STEAM HEATING AEPARATUS.

Patented May 14, 1889 `.ions

l Application led May l2, 1888.

Be it known that I, JOHN .'l`. PINE, of the city and State of New York, have invented an- Improvement in Steam-Heating' Apparatus, of which the following is a specification.

heightl of water in the vessel or reservoir lreceiving thewater of ctnnlensation. l make use of any ordinary*steam-pump,,and the.

. steam'to the engine of the pump is regulated by a valve controlled by a piston within a nyllnder separate from the reservoir into which the water ot' condensation passes.

ln instances where the supply ol' steam to the engine has been regulated by a float; such iioat isiliable to leak or to become injured and vunreliable in operation. ln consequence ot using a vessel that is separate irom the reservoir I am enabled to employ,:Loup-leather piston for the water to act upon, beeause such water'remains at or about the temperature ot the atmosphere, whereas it' the Cylinder and piston were wit-hin the reservoir they would be exposed tothe heat oi' thewnter et' eondensationthat would quickly injure the eupleather packing.

.In the drawings, lfig'ure l is an elevati/elliot' the pump and a section olf the cylinder eontaining the moving' piston, and Fig. 2 is a seetion ot' the valve made use ot loiadmitting f steam to the engine.

4.lhe steain-eyliinlert, Yaive-ehest il', pistou'- rod l), pump l, and air-vessel li are oi. ordinary construction, and the water of condensation which runs into the 'receiving-pipo i?. or into a reservoir otany 'suitable size, as indieatedby the dotted iines, is drawn oit by the pump vt. lirou' .;l1..thepipe l,` and l'roin'the pump s :'oreed through the pipe lil into tho boiler, generator, or holder oi.' any desired eharaufter.

initiates within the reservoir or pipe Ait also rises in the eylinderhl land lifts the piston N and allows the lever )l to deseend and supply more steam to the engine and cause such engine' and pump to work tnster, and when the water descends in the reservoir or pipe A it also descends in the cylinder M', and the pis- 'N slidintt` freelv within sueh evlinder'ltl and 3 i, u i

ton N moves downwardl')Y and by the ehainw gives motion to the leve-r n1 and steam-valve to lessen'the quantity ot steam passing, t0 the engine and Cause the pumping-engine to run more slowly.

'lhe steain-valve l( is withina suitable ease,

' l, and the steam-'valve is balanced, in eonsee quenee oi' beinj.,r made oi' the two valves a a,

upon the Astein Il, andthe valves close upon 'the valve-seats e e, and there is an arm, f, projeetine,r from the axis o ot' the iei'er lin., which arm f passes through an eye in the Stein I), and there is a packing around the axis g, so that the same is made steanntight, but is free to turn with but little friction, and this Construct-ion renders it unneeessary to make use olf any packing around the valve-stein b.

.l make use of a pressure-gemelli, connected by a branch pipe nud cook to thepipe l), and,

this pressuregage indieates thepressure of the column ot water wilhin *the pipe l) and eylinder lil', and in f-nse'ot' n eeidentto any partei' the apparatus thisIv gage will ini'iieate any increase in the water-'level ot" the altha- .ratus v i `ln consequence ot the siifanvrali'e being balanced and there beine4r but little trietion. upon the parts that. aetunte the vali'e said valve will be moved lrra slight change in the watelr-levehand there is but little friet-ion botween the eupleat.herpacking of the piston N and theevlinder M, and' this cup-leatherpack` in g' will not be exposed to lient, as there will be no Circulation of water -into or ont of the cylinder ]\l exeept that whieh results from the IDG rise and fall of the water-level, as the hot water of condensation runs into the pipe o1' reservoir A, and is thence taken to the pump Il.'

I claim as my inventionl. The combination, with the steam-pump, steam-Supply pipe, and valve for the Same, of the reservoir for receiving the water of condensation, the separate cylinder M, and the pipe L, leading from the same to the reservoir', and a piston Within the cylinder M, and a connection from the saine to the level' of ille steam-Valve, substantially as and f' o1' the pui'- poses Set forth.
